stop too often, this could be due to deterioration of
the saw blade or that it has come across wood that has
become excessively hard over time.
In any of these cases, we recommend reducing the
cutting depth to 34 mm and carrying out the operation
in two stages.
WITH THE DIAMOND-TIPPED BLADE:
Enables old wood window frames to be removed for
renovation. To do this, make a cut in the wall where
the frame is seated, parallel to its front and along its
entire edge (Figs. 2 and 7). This allows you to later
cut the jambs and remove the frame from its housing.
Diamond disk of D.180 7040329 for direct masonry
cutting. It may be used to cut brick, breeze blocks,
terrazzo, clinker, concrete, granite, ceramics, porcelain
and stoneware.
While working with the diamond-tipped blade, you
must follow these instructions:
• The working pressure must be similar to that exerted
by the weight of the machine itself.
• Always keep the blade perpendicular to the surface
you are cutting. Do not cut at an angle.
• Stop every so often and allow the machine to operate
without a load, which permits the blade to cool down.
5. ON/OFF SWITCH
The switch found on the grip allows you to start or stop
the machine without letting go.
To prevent this switch from being activated acciden-
tally, it can only function if the safety catch has first
been pressed.
6. CONNECTING THE DUST COLLECTOR
• Cutting building materials produces a large amount
of dust, therefore it is essential that the machine be
connected to an aspirator.
It is also recommended to connect the machine to a dust
collection system when using the saw blade on wood.
To connect the machine to Virutex AS182K, AS282K,
AS382L or ASC682 vacuum cleaners, or to another
external collection source, one end of the suction
tube 7045832 included on the appliance should be
connected to the dust collector connection (C, Fig.
3) on the machine and the other end to the chosen
external collection source.
7. ADJUSTING THE CUTTING DEPTH
Unplug the machine from the electrical
outlet before making any adjustments on it.
To adjust the cut depth, keep in mind the diameter of
8
the blade you are using.
The saw blade has a diameter of 200 mm, and the
diamond-tipped blade a diameter of 180 mm.
The index (A3, Fig. 1) shows the gauge, with one arrow
indicating the cutting depth for the 200 mm blade,
and the other arrow indicating the depth for the 180
mm blade.
To adjust the cutting depth, loosen the knob (A, Fig. 1),
move the stop rule (O, Fig. 1) to the desired depth on
the gauge and retighten the knob (A, Fig. 1).
When cutting a seated frame with the saw blade, always
measure the width of the frame and avoid exceeding
this depth to prevent damage to the blade.
8. CUTTING
WITH THE HARD METAL SAW BLADE:
Before proceeding to cut a frame or crossbeam, exa-
mine it very carefully and remove all screws, nails and
metal objects embedded in the cutting area that might
damage the saw blade.
Position the machine so that its base rests against the
wall and its front against the frame. Gently push the
machine forward against the frame until it reaches the
maximum cutting depth and move the machine slowly
to cut along the first side of the frame.
Repeat the same procedure on the three remaining
sides of the frame.
To assist with its lateral movement, the machine is
equipped with two support rollers (B, Fig. 2 and 3) that
prevent it from becoming stuck when it encounters
erosion or paint defects on the old frame.
With the hard metal saw blade and the front fence:
Old frames may be cut using the front fence as a
reference (EF, Fig. 3 and 6) on the inside of the frame
being cut (Fig. 3).
To mount the front fence support (S, Fig. 6), unscrew
the two screws (K, Fig. 6) that fasten the handle and
insert the fence support between the base and the
handle, making sure that it rests correctly on the base.
Place the support caps (J, Fig. 6) on the support and
attach it onto the base, using the screws (K, Fig. 6).
Next, position the front fence (EF, Fig. 6) at the mea-
surement for the cut you wish to make in the frame,
as indicated on the millimetre gauge located on each
side of the support (see the zoom, Fig. 6), and fasten
it in place using the knobs (L, Fig. 6).
Once the front fence has been adjusted, you may cut
the frame, using the front fence as a guide on the inside
of the frame (Fig. 3).
WITH THE DIAMOND-TIPPED BLADE:
In order to remove the old frames, first make a cut in
the wall where the frame is seated, parallel to its front
and along its entire edge (Fig. 2).
Next, cut the four corners of the frame, as explained
later in this section and as indicated in Fig. 7. Finally,
